Level 1 sweep and inspection to the NFPA 211 annual standard - flue, crown, cap, and flashing checked and photographed
Chimney sweep logs do not sweep chimneys. They loosen some creosote - which then falls where a brush and vacuum still have to collect it.

AfterFast, Reliable Chimney Inspection Across San Dimas
A chimney inspection in San Dimas typically costs $189 – $389 depending on the level of inspection required, and most appointments at homes throughout the city are completed in under two hours. We work throughout San Dimas weekly, from the Horsethief Canyon foothills down to the flats near Bonita Avenue, and we know what these chimneys look like inside. If you need an inspection, call (336) 863-3889 and a live person will answer, no matter the hour.
Why Alcott Chimney Sweep Is San Dimas’s Preferred Chimney Inspection Company
Ruben Castellano has built this company on a simple idea: you should know exactly who is coming to your door and exactly what they found, with evidence you can see. Before any appointment in San Dimas, you receive the technician’s name and photo by text or email. When they arrive, they show a photo ID badge. Every time, no exceptions. That’s the Threshold Standard, and it matters in a city where homeowners tell us they have opened the door to strangers far too often.
Our reputation in San Dimas comes from work, not words. We have inspected hundreds of the tract ranch and split-level chimneys that dominate neighborhoods from the 210 corridor up through the hillside streets, and we know the failure patterns by heart. A clay tile liner in a 1972 San Dimas split-level cracks differently than one in a 1986 La Verne ranch, and our written reports reflect that.
Every Chimney Inspection our team performs in San Dimas includes camera footage you watch with us, a written price before any repair work begins, and a written guarantee on every repair. If a repair fails within 365 days, the second visit is free. That’s the Done Right Promise.
Scheduling and dispatch are coordinated from our Los Angeles office, and crews serve San Dimas locally throughout the week.
Chimney Fire in San Dimas
A chimney fire in San Dimas is the result of creosote, the tar-like buildup that forms when wood smoke cools inside the flue, igniting at temperatures that can exceed 2,000°F. In San Dimas, where foothill homes sit inside a Very High Fire Hazard Severity Zone, a chimney fire isn’t just a structural problem. It can throw embers onto a shake roof or into dry brush, and with Santa Ana winds funneling down the San Gabriel foothills, that becomes a neighborhood risk in minutes. If you suspect a chimney fire, call 911 first. Then call us at (336) 863-3889 to inspect the damage before the next burn.
What a chimney fire inspection in San Dimas involves: a full internal evaluation of the flue, smoke chamber, damper, and cap, looking for the telltale signs: puffed or cracked flue tiles, honeycomb creosote, warped damper components, and heat stress on the crown. We do not guess. A camera goes down the flue and you watch the footage with us, frame by frame if you want.
What We Check After a Chimney Fire
The flue liner takes the brunt of the damage. In San Dimas’s 1960s – 80s homes, original clay tile liners often crack from thermal shock during a chimney fire, even if the fire was brief. Cracked tiles expose framing members to future heat transfer. We inspect every tile joint with magnification.
The crown and spark arrestor (if present) also get close attention. A chimney fire can warp the metal screen of a spark arrestor or crack the concrete crown, opening a path for water and embers. In San Dimas, where the Santa Anas push embers hard, a damaged spark arrestor is a genuine fire hazard.
Cost to Inspect a San Dimas Chimney After a Fire
A post-chimney-fire inspection in San Dimas typically runs $249 – $389. This includes full camera documentation and a written report with photos. If repairs are needed, you’ll get a written price before any work starts, and you’ll see the damage yourself before you’re asked to approve anything.
Level 2 Chimney Inspection in San Dimas
A Level 2 Chimney Inspection in San Dimas is the standard inspection for any home where something changed: a new appliance installed, a property sale, a chimney fire, or an earthquake. It includes everything in a Level 1 inspection, plus the camera scan of the entire flue interior and the accessible portions of the exterior. In San Dimas, where the 1960s – 80s housing stock is aging out of its original clay liners and many homes are changing hands, Level 2 is the inspection we recommend most often. It typically costs $249 – $389.
Real estate transactions in San Dimas almost always trigger a Level 2 inspection, and we work with buyers and sellers across the city. The report we produce is detailed enough for escrow and clear enough for a first-time buyer to read without a translator.
What a Level 2 Finds That a Level 1 Cannot
A Level 1 inspection is visual and covers the accessible surfaces: what the tech can see from the firebox and the roof. But 80% of the flue interior is not accessible to the naked eye. The camera sees it all. Cracked clay tiles, deteriorated mortar joints, water intrusion from a failed crown, and wildlife debris all live in the parts of the flue you cannot see from either end.
In Horsethief Canyon and other equestrian-zoned tracts, we regularly find nests wedged above the damper. A Level 2 camera catches this in a minute. A Level 1 inspection can miss it entirely, and then the homeowner lights the first fire of fall with a starling nest above the damper.
When San Dimas Homes Need a Level 2
Three situations matter most in San Dimas. First, any real estate transaction. Second, any appliance or liner change. Third, after any seismic event strong enough to rattle the hillside homes. A 4.0 quake on the Sierra Madre fault zone can shift a masonry chimney enough to crack a tile liner. We inspect, we document, and we give you the footage.
Trusted Brands We Service in San Dimas
We carry and install the same materials chimney professionals specify, not box-store substitutes. For San Dimas homes, that typically means DuraFlex stainless liner systems for cracked clay tile replacement and HeatShield resurfacing for liners with early-stage joint deterioration. We also stock Copperfield caps, which matter more in San Dimas than in flatland cities because our foothill homes need serious protection against wind-driven embers and debris from the San Gabriel Mountains. When we recommend a brand, it’s because that brand fits the specific chimney and the specific problem we showed you on camera.
Common Chimney Inspection Problems We See in San Dimas Homes
- Cracked clay tile liners in 1960s – 80s ranch and split-level homes. Decades of thermal cycling, where the flue heats and cools with each fire, eventually cracks the original clay tiles. In San Dimas’s tract-era housing stock, this is the single most common finding, and it often means creosote and heat can reach framing the homeowner cannot see.
- Wildlife nesting in flues left idle through spring and summer. San Dimas winters are mild enough that chimneys sit damp and unused for months, which makes them ideal for swallows and starlings. The foothill tracts near Horsethief Canyon see this more than the valley floor, and a nest above the damper is a fire hazard you cannot see from the hearth.
- External wildfire ash and char inside the chimney, not interior creosote. Homes in the northern hillside tracts closest to the Angeles National Forest boundary frequently show ash residue inside the flue from external wildfire events. This is not creosote from your fires. It is evidence of ember intrusion and a compromised crown or spark arrestor, and it changes the urgency conversation before the next Santa Ana season.
- Deteriorating mortar at the crown and shoulder. San Dimas sits at the base of the San Gabriels, and the seasonal wet-dry cycle plus wind-driven debris takes a real toll on exposed mortar. Water gets in, freezes in cold snaps, and widens the cracks. We rarely inspect a San Dimas chimney over 40 years old that doesn’t have some mortar deterioration.
Pricing for Chimney Inspection in San Dimas, CA
A standard Level 1 chimney inspection in San Dimas typically runs $189 – $249. A Level 2 inspection with full camera documentation runs $249 – $389. A Level 3 inspection, which is reserved for cases where structural damage is suspected and part of the chimney may need to be partially dismantled, is priced per job after the Level 2 findings are reviewed. What affects your price in San Dimas: the height and pitch of the roof (hillside homes often require different ladder and safety setups), the condition of the roof surface, and the number of flues. We give you a written price before any work begins, and the estimate is always free. Call (336) 863-3889 for your exact quote.

FAQs About Chimney Inspection in San Dimas
Yes, because the risk in San Dimas isn’t just about how often you burned. Homes near the base of the San Gabriel Mountains collect wind-driven debris on rooftops, and idle flues become nesting sites for swallows and starlings through spring and summer. A chimney that sat unused since February can be fully obstructed by September. An inspection confirms the flue is clear and the liner is intact before the first cold snap. Call (336) 863-3889 and we’ll schedule around your availability.
A Level 1 inspection is a visual check of the accessible surfaces and typically costs $189 – $249 in San Dimas. A Level 2 inspection adds a full camera scan of the flue interior and the accessible exterior, and costs $249 – $389. Most San Dimas homes need a Level 2 if the home is being sold, if you have never had the chimney inspected, or if you suspect any damage. If your home is 40 – 60 years old with an original clay liner, Level 2 is almost always the right call.
In San Dimas, this is usually external wildfire residue, not interior burning. Homes in the northern hillside tracts close to the Angeles National Forest boundary often show ash and char material inside the flue from ember intrusion during wildfire events. It’s a sign your crown, flashing, or spark arrestor may be compromised. This is precisely the kind of finding that separates a knowledgeable San Dimas inspection from a generic one, and we’ll show you the footage before recommending anything.
Yes. San Dimas sits inside a Very High Fire Hazard Severity Zone, and LA County mandates spark arrestors on all chimney flues. A functioning spark arrestor with clean mesh prevents embers from escaping your chimney and also blocks wind-driven debris from entering it. During Santa Ana wind events, a damaged or missing spark arrestor is a real liability. We inspect spark arrestors on every job and stock Copperfield replacements locally.
You watch the camera footage with us. We never recommend a liner replacement or any repair without showing you the crack, the deterioration, or the damage on screen. In Horsethief Canyon, our tech opened a 1970s split-level with a heavy-use wood fireplace and found a cracked clay flue liner, first-degree creosote glazing the smoke chamber, and a swallow nest wedged above the damper. We ran a Level 2 inspection with camera footage the homeowner watched in real time, then fitted a DuraFlex stainless liner and a Copperfield cap, no upcharge recommended until they saw the crack themselves. That’s the standard on every San Dimas inspection. Call (336) 863-3889 and we’ll show you exactly what we see.
